The Knight of Darkness crushes crime in two thrilling mysteries by Walter Gibson writing as "Maxwell Grant." First, "The Third Skull" holds the secret to a hidden fortune, but only The Shadow can decipher its cryptic message. Then, as millionaire Lamont Cranston and businessman Henry Arnaud, the Dark Avenger journeys to a "Realm of Doom" to engage the last of The Hand's murderous Fingers in a battle to the death!

This classic pulp reprint showcases both of George Rozen's color pulp covers, the original interior illustrations by Tom Lovell and Edd Cartier and commentary by Will Murray.
